Re: Armour Metallurgy Properities

The numbers are not hard and fast for physical properties. It depends on the hardness level and the heat treatments. For example, the typical tensile strength of armor grade steels hardened to 250 brinel hardness, is about 75 kg/mm2. If the hardness is 300 BH then the TS increases to about 90 kg/mm2...

Re: Tsushima

In recent times USN personal from the USS Nimitz volunteered to repaint and do other restoration work on Mikasa while the air wing was based at Atsugi. It is kind of fitting that they were from USS Nimitz, because Admiral Nimitz himself was a leading force to preserving Mikasa during the decades fol...

Re: Tsushima

The Russian shooting wasn't bad, but not as good as the Japanese. Mikasa was reportedly hit 30 times at Tsushima. However, the shells mostly broke up against Mikasa's KC armour. One of the lessons learned from the Yellow Sea battle was the inadequacy of the munitions. It was one reason why Togo adop...

Re: Tsushima

It seems to me that this became a habit of theirs! It's true that Japan planned surprise attacks in both the cases of the Russo-Japanese war and in Dec 1941. However, I don't think it was common practice. In 1894 they sent troops to Korea in response to China sending in troops in violation of treat...

Re: Tsushima

Tsushima had large influence on further ship development (just after Yellow Sea and Tsushima battles, old pre-dreadnoughts were superceeded by dreadnoughts) and still influenced the Japanese naval strategy (and constructions) up to WWII. British officers on board Togo's ships (Japan officers were m...

Re: Tsushima

Here's a photo tour I found of Togo's flagship the Mikasa. https://www.cnet.com/pictures/take-a-tour-of-the-114-year-old-japanese-battleship-mikasa-pictures/45/ Across the stern is Mikasa spelled in hiragana. It reads from right to left, rather than the modern convention of left to right. Usually ka...

Tsushima

Today not only marks the anniversary of the sinking of the Bismarck but it is also the anniversary of the Battle of Tsushima. During 1900 Russia occupied Manchuria. This posed a dire threat to Japan because it meant that Russia could gain control of Korea and then eventually Japan. Japan tried to re...

Re: Escape from the Scheer?

I was not clear on the date of this encounter from the video. Was it on the 5th? It is not mentioned in the KTB for the 5th or in the action report of the battle with HX84 authored by Krancke. The convoy was located by the Scheer's scout plane 88 nautical miles away at 13:00. This presented Krancke ...

Re: the Twins plus Bismarck

Gentlemen, I'm sure we may ave discussed this before somewhere, but if the Bismarck had made it back to Brest and then came out with the twins it would have caused a mighty problem for the RN. But what about the logistics of keeping three large ships at sea, with very few 'friendly' ports to go to ...

Re: China and the Biden Administration

What has occurred and continues to occur is absolutely unacceptable . Not only is it just about a monumentally stupid policy agenda. Not only was the coup d eta unacceptable, but also the trampling of US Constitution in its wake. Unless there is free speech for all, including unpolite speech, there ...

Re: China and the Biden Administration

Don't forget Japan. The whole reason Japan was in Korea and Manchuria 100+ years ago was because what happens in Korea finds its way across the strait to Kyushu and then to Honshu. Since the war, Japan and South Korea, and Taiwan, have been protected by the US nuclear umbrella. It has brought a stab...

Re: German Intelligence Estimates on RN BB Dispositions

Intel could use three basic tools to retain a fairly good picture of enemy dispositions, especially of major warships; not including the cloak and dagger, and the femme fatale, stuff. 1) Direct observation. 2) Air reconnaissance. 3) Signal Intel. First, direct observation would be a standard practic...

Gentlemen, Re backing plates, when the Germans designed their U boat pens I believe they deliberately left a space between the outside and inner reinforced concrete roof to absorb the effect of any bomb that might penetrate the upper roof, would this method give the same protection using steel plat...

Re: A Force Z What If

Both PoW and Repulse had type 284 gunnery radars. In late 1941 the type 284 was not all that capable, however. It was not yet capable of blind fire being with out lobe switching, and the effective range to a battleship was still only about 20,000 yards. Perhaps 25,000 yards absolute max. However, if...
